Fracture aperture against orientation. a Rose diagrams showing the orientation of induced fractures (orange) and borehole breakouts (light blue) along the well, and strike direction of all fractures (white). Arrows show direction of SHmax derived from drilling-induced fractures—dark red, SHmax derived from borehole breakouts—dark blue. Line diagrams below show b count, c cumulative fracture aperture, d mean fracture aperture of open fractures versus fracture strike direction (0–180°). Fracture aperture is normalised to the widest fracture. Dashed horizontal lines show the mean value of the boreholes
